On the Spot trading dashboard, once you have selected a currency, all possible trading pairs containing that currency is displayed at the top. For example:
USD is being selected. BTCUSD, in turn, is displayed by default as the main trading pair of USD. ETHUSD and BCHUSD are displayed on its right.
Things are slightly different with the Margin trading dashboard.
Only BTCUSD is displayed. Other products have to be added manually.
Click Manage Products on the top right.
Click on any product to add it to your dashboard. Alternatively, you can hide them by clicking the Hide button. Click Done once you finish.
Here we have added BTCSGD, ETHHKD, and BCHJPY, all under the currency account of USD. This means you can use USD as the funding currency for BTCSGD, ETHHKD, and BCHJPY margin trades. We call this feature multicurrency trading. Margin and P&L are calculated using normally with the quote currency of the product, then converted to funding currency using global FX rate at the time.
